The ink isn’t dry yet, and we haven’t had a chance to go through it in detail, but be aware that US EPA has officially released its Nanoscale Materials Stewardship Program.  Details on the program can be found here, and prior discussion can be found here

The Federal Register notice on the program’s release is here (73 FR 4861), and addresses the comments submitted by interested parties during the draft phase.

More information will come as we have a chance to parse the material.
